Description

Technical Field

[0001] The invention relates to the field of gears, and in particular to a wear-resistant, corrosion-resistant, high-strength gearbox gear. Background Art

[0002] As a key component in the transmission system, gearbox gears need to withstand large loads and friction, so they have extremely high requirements for wear resistance and corrosion resistance. Traditional gearbox gears are usually made of integral materials. Once the surface teeth are severely worn, the entire gear needs to be replaced, which not only increases maintenance costs, but also causes a waste of resources.

[0003] In order to solve this problem, some detachable gearbox gears have appeared on the market, but they are often complex in structure and prone to misalignment or looseness during assembly, thus affecting the transmission effect and durability of the gears. In addition, these gears are also insufficient in corrosion resistance treatment, and are prone to corrosion after long-term use, reducing the service life of the gears.

[0004] Therefore, there is an urgent need for a high-strength gearbox gear with simple structure, stable assembly, wear resistance and corrosion resistance to meet the needs of modern transmission systems. Summary of the invention

[0005] The object of the present invention is to provide a wear-resistant, corrosion-resistant, high-strength gearbox gear to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a wear-resistant and corrosion-resistant high-strength gearbox gear, comprising a wear-resistant toothed disc, wherein the top surface and the bottom surface of the wear-resistant toothed disc are provided with an assembly groove, and an assembly plate one and an assembly plate two are respectively inserted into the two assembly grooves, a screw is inserted into the surface of the assembly plate one, one end of the screw is fixed to the surface of the assembly plate two, and the other end of the screw is sleeved with a nut threaded thereon.

[0007] Preferably, the assembly groove is a circular groove, the assembly plate one and the assembly plate two are both "convex" shaped circular ring plates, the protruding parts of the assembly plate one and the assembly plate two are inserted into the assembly groove, and the surfaces of the assembly plate one and the assembly plate two are both integrally formed with a shaft sleeve.

[0008] Preferably, a positioning slot is provided on the surface of the assembling groove, and the positioning slot is a square slot. There are multiple positioning slots, and the multiple positioning slots are arranged and distributed at equal distances and sizes along the inner ring mouth of the assembling groove. A positioning block is inserted into the inside of the positioning slot, and the positioning block matches the positioning slot, and the positioning block and the positioning slot correspond one to one. There are two groups of positioning blocks, and the two groups of positioning blocks are respectively integrally formed on the surfaces of the assembling plate one and the assembling plate two.

[0009] Preferably, the outer ring surfaces of the assembling plates 1 and 2 are both sleeved and fixed with rubber rings, which are circular ring plates with arc-shaped cross-sections. The rubber rings are inserted into the card slots, which are opened on the surface of the assembling slots and are annular grooves.

[0010] Preferably, sealing gaskets are fixed on the surfaces of the assembling plate 1 and the assembling plate 2, and the sealing gaskets are annular plates.

[0011] Preferably, a through hole is provided on the surface of the assembly plate 1, and lead-in grooves are provided at both ends of the through hole. The lead-in grooves are hemispherical grooves, and the diameter of the lead-in grooves is larger than the aperture of the through hole. Rubber pads and rubber balls are respectively fixed on both ends of the screw, and the rubber pads are inserted into one lead-in groove, and the rubber balls are inserted into the other lead-in groove.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The wear-resistant and corrosion-resistant high-strength gearbox gear proposed by the present invention sets the wear-resistant toothed disc and the assembly plate as an assembling structure, so that when the teeth on the surface of the wear-resistant toothed disc are severely worn, the wear-resistant toothed disc can be replaced alone without replacing the entire gear. This greatly reduces the maintenance cost of the gear and reduces the waste of resources. A positioning plug is provided on the assembly plate, which matches the positioning slot on the wear-resistant toothed disc to ensure that the assembly plate will not rotate after being inserted into the assembly slot, thereby ensuring the stability of the gear and the transmission effect. Rubber pads and rubber sleeve balls are respectively fixed on both ends of the screw, which can not only play a temporary limit role in the assembly process, but also act as elastic pads after the nut is screwed and locked, thereby improving the utilization rate of parts and the stability of the overall structure.

[0023] See also Figure 1-Figure 7 The present invention provides a technical solution: a wear-resistant and corrosion-resistant high-strength gearbox gear, comprising a wear-resistant toothed disc 1, the top surface of the wear-resistant toothed disc 1 and the bottom surface of the wear-resistant toothed disc 1 are both provided with an assembling groove 2, an assembling plate 1 4 and an assembling plate 2 5 are respectively inserted into the two assembling grooves 2, the assembling groove 2 is an annular groove, the assembling plate 1 4 and the assembling plate 2 5 are both "convex" shaped annular plates, the protruding parts of the assembling plate 1 4 and the assembling plate 2 5 are inserted into the assembling groove 2, and the surface of the assembling plate 1 4 and the assembling plate 2 5 The surface is integrally formed with an axis sleeve; a positioning slot 3 is opened on the surface of the assembling groove 2, and the positioning slot 3 is a square slot. There are multiple positioning slots 3, and the multiple positioning slots 3 are arranged and distributed at equal distances and sizes along the inner ring mouth of the assembling groove 2. A positioning plug 6 is inserted into the inside of the positioning slot 3, and the positioning block 6 matches the positioning slot 3, and the positioning block 6 and the positioning slot 3 correspond one to one. There are two groups of positioning blocks 6, and the two groups of positioning blocks 6 are respectively integrally formed on the surface of the assembling plate 1 4 and the assembling plate 2 5. The wear-resistant toothed disc 1 and the assembling plate 1 4 and the assembling plate 2 5 are set as an assembleable structure so that when the teeth on the surface of the wear-resistant toothed disc 1 are severely worn, the wear-resistant toothed disc 1 can be replaced alone, and the assembling plate 1 4 and the assembling plate 2 5 used to connect the shaft body do not need to be replaced, which will reduce the maintenance cost of the gear. The wear-resistant toothed disc 1 is made of wear-resistant steel, and a corrosion-resistant coating is sprayed on the surface of the wear-resistant toothed disc 1, which plays an anti-corrosion role when the wear-resistant toothed disc 1 is not in use. After the wear-resistant toothed disc 1 is used, lubricating oil is applied regularly for anti-corrosion; when the assembling plate 1 4 and the assembling plate 2 5 are inserted into the corresponding assembling groove 2, the positioning block 6 is inserted into the corresponding positioning slot 3, which prevents the assembling plate 1 4 and the assembling plate 2 5 from rotating in the corresponding assembling groove 2.

[0024] The outer ring surfaces of the assembly plate 1 4 and the assembly plate 2 5 are both sleeved with a rubber ring 7, which is a circular ring plate with an arc-shaped cross section. The rubber ring 7 is inserted into the card slot 8, which is provided on the surface of the assembly slot 2 and is an annular groove. The surfaces of the assembly plate 1 4 and the assembly plate 2 5 are both fixed with a sealing gasket 9, which is an annular plate. When the assembly plate 1 4 and the assembly plate 2 5 are inserted into the corresponding assembly slot 2, the rubber ring 7 is inserted into the corresponding card slot 8, so that the temporary limit of the assembly plate 1 4 and the assembly plate 2 5 after being pushed into the assembly slot 2 is realized, and the sealing gasket 9 is used to fill the gap between the assembly plate 1 4 and the assembly plate 2 5.

[0025] A screw 12 is inserted into the surface of the assembling plate 1 4, one end of the screw 12 is fixed on the surface of the assembling plate 2 5, and a nut 15 is threaded on the other end of the screw 12. A through hole 11 is provided on the surface of the assembling plate 1 4, and both ends of the through hole 11 are provided with an introduction groove 10, the introduction groove 10 is a hemispherical groove, and the diameter of the introduction groove 10 is larger than the aperture of the through hole 11, and the two ends of the screw 12 are respectively fixed with a rubber pad 13 and a rubber ball 14, the rubber pad 13 is inserted into one introduction groove 10, and the rubber ball 14 is inserted into the other introduction groove 10.

[0026] When the assembling plate 1 4 and the assembling plate 2 5 are inserted into the corresponding assembling grooves 2, the screw 12 passes through the corresponding through hole 11, and the rubber pad 13 and the rubber ball 14 are respectively inserted into the two introduction grooves 10 to realize temporary limiting of the assembling plate 1 4 and the assembling plate 2 5 during assembly. In order to strengthen the connection between the assembling plate 1 4 and the assembling plate 2 5, the nut 15 is threaded on the top of the screw 12 and then screwed and locked. At this time, the rubber pad 13 and the rubber ball 14 are under pressure and act as elastic pads. In this way, the rubber pad 13 and the rubber ball 14 can be used for multiple purposes.

[0027] The usage process is as follows:

[0028] Confirm that the wear-resistant toothed disc 1, assembly plate 1 4, assembly plate 2 5, positioning plug 6, rubber ring 7, sealing gasket 9, screw 12, rubber pad 13, rubber sleeve ball 14 and nut 15 are complete and not damaged. Ensure that the surfaces of all parts are clean and free of dust, oil or other impurities for better assembly and fixation. Insert assembly plate 1 4 and assembly plate 2 5 into the assembly groove 2 on the top and bottom surfaces of the wear-resistant toothed disc 1 respectively. Ensure that the positioning plug 6 is accurately inserted into the corresponding positioning slot 3 to prevent assembly plate 1 4 and assembly plate 2 5 from rotating in the assembly groove 2. Insert the rubber ring 7 into the corresponding card slot 8 to achieve temporary limit after assembly plate 1 4 and assembly plate 2 5 are pushed into the assembly groove 2. Install the sealing gasket 9 on the surface of assembly plate 1 4 and assembly plate 2 5 to fill the gap between the assembly plates and enhance the sealing. Fix one end of the screw 12 on the surface of the assembly plate 2 5, and pass the other end through the through hole 11 of the assembly plate 1 4. Make sure that the rubber pad 13 and the rubber ball sleeve 14 are respectively inserted into the two guide grooves 10 on the surface of the assembly plate 1 4 to achieve temporary limit when assembling the assembly plates 1 4 and 2 5. Screw the nut 15 onto the top of the screw 12 and tighten it. During the screwing process, make sure that the rubber pad 13 and the rubber ball sleeve 14 are under pressure to act as elastic pads to provide additional buffering and fixing effects. Check whether all connection parts are firm and ensure that there is no looseness or misalignment. Gently shake the assembly plate 1 4 and the assembly plate 2 5 to confirm that they are firmly fixed on the wear-resistant gear disc 1.

[0029] After the wear-resistant toothed disc 1 is used, lubrication oil should be applied regularly for corrosion prevention to extend the service life. The wear of the teeth of the wear-resistant toothed disc 1 should be checked regularly. If the wear is serious, the wear-resistant toothed disc 1 should be replaced alone without replacing the assembly plate 1 4 and the assembly plate 2 5. If the rubber ring 7, sealing gasket 9, rubber pad 13 or rubber sleeve ball 14 are found to be aged or damaged, they should be replaced in time to ensure the normal operation of the equipment.
